Abstract

A shielded conductive path capable of being easily managed in terms of a length of a portion of a single core wire protruding from a shield pipe includes a shield pipe electromagnetically shielding a plurality of single core wires inserted therein and a spacer having insertion holes individually receiving the single core wires. Each single core is made of a single conductor as a core wire. The spacer is fitted inside of the shield pipe while being restricted from displacement in directions perpendicular to an axial direction of the shield pipe.
